FRAMEWORK FOR ELEVATORS.

SPECIFICATION forming part of Letters Patent No. 498,576, dated May 30, 1893.

Application filed August 6, 1892.

..To all whom it may concern.-

Be it known that I, THOMAS F. SANFORD, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Framework for Elevators; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

My invention relates to structural improvements in the frame-work surrounding the shafts of elevators and consists of a novel arrangement by means of which the wire partitions are secured in place in an expeditious manner without recourse to bolting or riveting.

I will now minutely describe the manner in which I have carried out my invention and claim what I believe to be novel.

In the drawings, Figure 1 is a front elevation of a section of shafting with portions broken away showing arrangement of parts. Fig. 2 isa horizontal section of Fig. 1, and Fig. 3 is an enlarged detached View of myimprovement.

Referring to the drawings, 1 is the usual angle iron located at each corner of the elevator shaft. Between two of these angleirons are secured the partitions consisting of the wire-work 2, having their iron frame pieces 3, and 7 is the sliding door opening into the elevator. These frames surrounding the wire work are secured between and to the angle-irons 1, 1, by the double grooved iron strip 4, having on one side the narrow groove or channel 5, adapted for the snug reception Serial No. 442,859. (No model.)

of the edge of the angle iron 1, and on the other side the wider groove or channel 6 adapted in a similar manner for the reception of the side-pieces 3, carrying the wireork 2. These strips 4 can be forced in between the an'gle-iron 1, and the side-pieces 3' from the top and driven down in place thus securing the parts-together in a rigid manner without the necessity of either bolting or riveting. Neither the angle iron nor the frame is punctured or in any way mutilated thus avoiding any weakening of parts and the parts can in this manner be expeditiously put together and as quickly taken apart.

While I have shown my invention as applied to the frame-work of elevator shafting it is apparent that itis adapted for other and varied uses and in fact wherever portable partitions are to be removably joined to frame Work or other partitions of the same or dif ferent thickness the side grooves or channels and secured in this manner without bolts or rivets substantially as and for the purpose stated.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
